Archived [ARCHIVED THREAD] - Question about Rock River Arms' R-4 barrel
Posted: 1/13/2006 5:18:04 AM EDT
What is it for?  I can't think of a purpose for thinning the barrel in that spot.  Can a guru chime in?

Thanks,

YTDMan

Its for attaching the grenade launcher you dont have =  Its just decoration.
